2011 2ss manual

 

^^^x2 what yr and motor?

 

I thought about a handheld too until I had mine dyno'd. Then I figured I would get it dyno tuned, the only problem with that is every time I move I would have to get it tuned again.

 

Well, we are in 5th gen section, 5th gen V8 actually...

Why did my post go way over here?

 

You definitely don't want to get a hand held tuner. They will never serve justice against taking your car to a dyno shop to get it tuned.

 

so i'd have to get it dyno'd in order to take full advantage of the mods that i have?...and edog why would u have to get it dyno'd everytime you moved?

 

I live in Colorado Springs, thin air = less o2. When I go down to sea level there will be a signifigant change. Thats why our premium gas is 90-91 Octane vs 93 you can get at lower altitude. It is anti-knock and since there is less o2 to cause knock there is less of a need for octane to inhibit it (so I have figured from research).

Thats why my 1/4 mile time in my SS would be lower here than sea level, if I ever make it to a track and run it that is.

Also in the 67's carb, I had to put in smaller jets to account for the lower o2, just not enough for efficient fuel burning with the "sea level" jets. Also thats why the 67 ran hella rich on the dyno, so small jet= less fuel= better burn with less o2.

Now that being said I havent gotten it tuned yet and it is still a beast, but we are all on a level playing field here since nobody I know of has ever thought of an o2 injecter unless you consider nitrous, and then its all out the window.

 

Oh, so after all that the tune would just match up everything with the location of the car, and would need to be done after significant changes, be it altitude or better flow in/out of the engine since they both change the "chemistry" of the air mixtures.

 

what's the difference between the longtube and shorty headers?

 

Length, and shorties normally aren't very helpful so get longtube
